Our Intex pool is a round 18' metal frame. Probably should not leave up for winter but have no choice now. How can we get it ready for winter? Chemicals and amounts, covers, how much water left in? We removed everything attached to the pool and put in the plugs. So it is just the pool and water. We have never done this before and none of the post address this type of pool. Help please! It is now too cold to take down the pool. It is 3 years old and we fear it will tear. My husband drained and cleaned for days around labor day. Working 3 jobs and just didn't get to finish. Now we need to do this in Nov. and buy chemicals and covers. Thank you!
